Beit known that I.V Ouvrir B. Hensema.

a citizen of the United Stat, residing at near Qntario., in the countyof. San BernalA dino and State of California, have invented a new and useful Orchard Heatnof which the following is a specification.

This inveation relates to heaters for use in orchards and the lil.

The obiect of the invention is to provide a simply constructed and efficient heater of this character which may be readily* transported from place to platee M1617 which will effectively heat a large alena u'rtminding it with a minimum consumption of fuel.

With the foregoing and other objects in view which will appear as the description proceeds. the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being `understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a central vertical section of the casing constituting part of this heater with the other parts shown in side elevation and partly in section.

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1.

Fig. 3 is a view similar to Fig. 1, showing a modified form of the invention, and

Fig. 4 is a horizontal section taken on the line 4 4 of Fig. 3.

In the embodiment illustrated in Figs. 1 and 2, a sheet metal casing 1 is shown which may be circular in cross section or of any other desired configuration, and which is equipped with a removable dome-like cover 2.

Mounted in the casing 1 is an oil burner 5 having a supply pipe 6 leading from a container (not shown) and which extends into the casing at a point near the bottom thereof. This inlet pipe 6 is connected with an upright pipe 7 by an elbow coupling 7*. This upright pipe 7 merges at its upper end into a U-shaped horizontally disposed pipc which includes legs 8 and 10 connected h v a. cross bar 9. A vertical pipe 11 is connected with the free end of leg 10 by a suitable elbow coupling and at its lower end is connected by a coupling 11a with a horizontally disposed pipe 12 having an apei'tlwe 13 in its upper wall for a purpose presently to her described.

Theheiri'aurr'tal pipe 12 is connected by an elbow 12% with an upright pipe 14 which extends to a, point naar the top of the casing' l amd is `proizfided near its upper end with a plurality 01E radially opening apertures 15' through the gas generated inthe harizomal pipes passes and is ignited.

In the4 use oithis heater. oit is fed in thxmughpiipe Gland passes up through pipe 7 aroUndethrdughf-the U-.lshaped pipe down t the veioatpipei 11 into the lower horizontal pipe.F `12` midis ignited at' 13, the flame formed by this ignition contacting with the upper horizontal pipe and with a plate 16 which connects the legs 8 and l() of the U-shaped pipe and the heat contacting with these members generates gas which flows down through pipe 11. enters pipe l2 and passes up through pipe 14 and is ignited at 15 by the fiame from below. This arrangement of pipes and the heat generated by the burning liquid fuel and the gas is extreme and passes out through apertures at the base of the top 2 to the surrounding atmosphere as Well as by radiation from the casing l so that a large area around the heater is heated sufficiently to prevent freezing in the orchard in which the device is located. It will also be seen that such a heater will consume a comparatively small amount of oil.

In the form of heater shown in Figs. 3 and 4 a easing 1il of sheet metal is shown equipped with a spider to 2L in which is mounted a burner in the orm of a coiled pipe 5*L having an aperture 18 in the upper wall of one of the lower parts of the coil as is shown clearly in Fig. 4, and through which the oil exudes and is ignited for heating the oil in the surrounding coils 17 and the gas passes upward through pipe 19 and is ignited at the upper end thereof. the flame formed at this end contacting with the top 2a and is diffused over a large area.

An inlet pipe 6al extends through one side wall of the casing 1'* and merges into the coil 5a at the upper portion thereof so that the oil entering through this pipe 6a will pass around through the respective coils 17 and that portion which passes through the aperture 18 will be ignited and heat the coil sufiiciently to generate gas which as above described passes out through pipe 19 and is ignited to form the heating llame.

This forni ofheeter like thetslown Figs. l and 2 is very simpleJ 'icdstuet'io-` utilizes u minimum amount of fuel, produces thereof, mnupright pipe Connected with seid a maximum amount ofheat andhoth of them muy be readily transpoted from place lll to plum to supply heat Where neededl.,

I claim l. A heater of the class described comprising n 'dieet metal casing having a spreaderlike closure at its upper end with heet ou'tlets et the bue@ of saidclosure, a ges generator mounted therein and including oil Conduitev arranged one above the other, ,the

lowermost having an opening positioned unler the upper and adapted for the `passage of fuel therethrough to be used in heating the oil in the pipes above to generate gas,

and a gas pipe leading from seid generator und having a burner at its upper end.

2. AV heater of the Aclass described zeom` prising a sheet metal oasing'han'ringa `removable overhunging yclosure etA its upper end with openings formed underv the overhanging, portion thereof, a ges generatm' mou'ted 1n lsind easing and comprising e, supplyplpe entering through one side well supply pipe, a` horizontelly disposed U- shaped pipe connected et one end with seid upright pipe, another pipe depending from the other'` end of Said U-shaped pipe, e horizontal pipe carried by seid depenwlingr pipe, an upstanding pipe leading from Smid last mentionedpipe and having e burner at its upper end, and an aperture in one of said lower pipes for the outlet of oil to be burned and by means of which the oil in the ot'hei` pipes is heated.

In testimony that I claim the foregoing as my own', I have hereto affixed my signature in the presence of two witnesses.
